[bldg-sim] Heat recovery: Any data on central water/sewer drain line temperatures from multi-family buildings?

[Brian Thornton]

I am looking for information on the temperatures of the waste water leaving
multi-family buildings.

 

We have looked at drain heat recovery at individual showers and units, and
found the space requirements (and placement of heat recovery equipment in
some other tenant/owner spaces) to be too big an obstacle.

 

I am wondering if there is enough heat to consider central heat recovery off
of the combined drain lines to pre-heat domestic hot water make-up.

 

Any one have history in trying such a heat recovery approach?

 

Brian
